CYLINDER SADDLE FOR HIGH-PRESSURE ARTICULA'I'ED LOCOMOTIVES.

Application filed July 7, 1927.

The object of my invention is to improve the construction of the frontcylinder saddle of a high pressure articulated locomotive.

The saddle is made in three sections, the central section being boltedto the side sections which contain the cylinders and their valve chests,the central section also acting as a support for the steam and exhaustpipes of the locomotive.

In the accompanying drawings:

Fig. 1 is an end view of my improved cyl inder saddle for the front endof a high pressure articulated locomotive;

Fig. 2 is a plan view of the central section;

Fig. 3 is a side View of the central section; and

Fig. 4 is a sectional View on the line 44, Fig. 1.

Each side section contains a cylinder 4, a valve chest 5, and an exhaustpassage 6. The side sections have vertical flanges 7 and 8. Thecentralsection 2 has flanges 9 at each side which are secured to theflanges 7 of the side sections by bolts 10, the parting line beingdirectly over the centre of each side frame 1.

The central section extends between the side frames and has flanges 11at each side which fit against the inner surfaces of the side frames andare secured together and to the side frames by bolts 12. In this type oflocomotive, the central section of the saddle is used only as a supportfor the overhanging side sections containing the cylinders and theirvalve chests, and in this instance has a support for the steam andexhaust pipes leading to and from the valve chests and the cylinders.

The central section has two seats 13 and 14 which are cast integral withsaid central section as clearly shown in Fig. 4, these seats beingconnected by an inclined reinforcing member 15. The seat 14 is at theforward end of the central section and is higher than the seat 13, theseat 14 supporting the central exhaust pipe at as shown by dotted linesin Fig. 1 which has branches bb connected to the exhaust passages 66 inthe cylinder saddle structure. This central exhaust pipe has extendedbase portions 6 which rest upon the seat 14 and are secured thereto bybolts or other fastenings.

Mounted on the seat 13 is the central steam pipe d, which has feet 6resting upon the seat 13, and bolts secure said pipe structure to theseat 13 of the saddle. The central steam pipe d has branches eeconnected by pipes f to Serial No. 204,102;

the steam passages of the steam chests 5. The steamsupply an'dexhaustpipes are shown by dotted lines in Fig. 1.

In order to reinforce the central structure so that it can properlysupport its load, I provide a horizontal plate 16 which extends fromside to side and end to end of the central structure, preferably on aline with the upper surface of the frame 1, and a horizontal plate 17extends from side to side and end to end of the central structurepreferably on a line with the lower ends of the frame 1. The centralstructure is also reinforced with ribs and fillets to add strengththereto.

Openings 18 are formed in the lower section and openings 19 in the uppersection of the central structure, so that access may'be had to theinterior of said structure. Other openings 20 are formed in the top ofthe section, while openings 21, shown by dotted lines in Fig. 3, areformed in the bottom section. By providing these openings, access may behad to all parts of theinterior of the central structure, the openingsalso reducing the weight of said central structure.

I claim:

1. The combination in a locomotive cylinder saddle, of a central sectionmounted in the main frames of the locomotive; side sections containingcylinders and overhanging said side frames; means for securing the saidside sections to the central section and to the side frames; and meanson said central section for supporting the steam and exhaust pipesleading to and from the valve chests of the cylinder sections.

2. The combination in a locomotive cylinder saddle for high pressurearticulated locomotives, of a central section and side sections, thecentral section extending between the side frames of the locomotive andhaving flanges bearing against the inner surfaces of the said sideframes, the cylinder sections being located outside of the main framesand having flanges bearing against the outside of the central section;bolts extending through the flanges and securing the sections of thesaddleto the frames, the central section and the side sections havingvertical flanges extending directly above the main frames; and boltssecuring the flanges to the said frames, said central section havingseats for the steam supply and exhaust pipes leading re spectively toand from thevalve chests of the cylinder saddle.

3. The combination in a locomotive cylinder saddle for high pressurearticulated locomotives, of a central section to which the side sectionscontaining the cylinders are secured, said central section having tWoseats, one seat being higher than the other, the high seat beingarranged to support the main exhaust pipe, and the low seat beingarranged to support the central steam pipe; and an inclined reinforcingmember connecting the two 10 seats.

4. The combination in a locomotive cylin- LAWRENCE W. HANCE.
